driving a serial synthesizer through speech-dispatcher

[John G Heim]

There would already be code in speakup to talk to different hardware 
synths. I don't know how portable that code is. But you could probably 
look at the speakup code to see how to set the speech rate for a 
liteTalk for example. If that code is portable, a large part of the work 
would already be done.
